what is detritus?
Detrius is fish poop and other organic material that is collecting and degrading causing nitrates.
You also mentioned you have a 30 gallon, is it one of those all in one nano's with chambers in the back? If so check the back chambers for detrius and old food and siphon out what you can. During water changes turn off your pumps, take a turkey baster and blast it into the chamber to get the detrius off the floor to rise into the water. Then take your siphon hose and siphon out the water in the chamber which in turn will take out the detrius. Also use the same scenario on in your display area, but blowing detrius off the LR and into the water column to be siphoned out.
